How did you go about matching with your rear springs in either case? I didn't. It was trial and error. In my opinion, the A-body Hotchkis leaf springs are a little too soft for how much it lowers the car. I'm thinking about adding a cheapo helper spring on them to prevent them from sagging when my trunk has a bunch of stuff in it. God forbid right now I even think about fitting a spare tire in the back. Part of the problem has to do with the offset wheels I have, but still.

MRGTX -- Your 1.08 TBs will be slight noticeable difference, but you'll probably realize that you could have gone a little stiffer with them, such as about 1.14-1.18, and you'll still have reasonable comfort. But, what tire aspect ratio are you going to run?... that'll make a difference in itself... 35-40-45-50-60-70 series tires? shorter aspect ratio sidewalls make for stiffer rides.
For leaf springs, either the Firm Feel handling leafs, or the Hothckis. If you get more serious for handling, you'll eventually make them stiffer.
For shocks, I'd highly recommend any of the multi-adjustable shocks (double adjustables) such as Viking, QA1, etc.... you won't regret it, and, you can fine-tune the ride and handling as you find best in comfort and, perhaps, occasional track lapping events.

You should be fine with this setup... (1.08 TBs and Hotchkis leafs) the Hotchkis leafs are suppoosed to guive a slight drop in ride height (check your snubber clearance in rear... probably OK.... but you'll really want to fine tune to your liking... so.. highly consider the double adjustable shocks (Viking, QA1, etc)... giving you the final say to suite your comfort. Also, pending how low you may go in the front with the TBS height adjustment, you may need to slightly shorten (cut) the front rubber snubbers on the LCAs.

have you ever though about running fiberglass leaf springs? you can then pick your rear rate you want I run hyperco 200lbs rears with sliders, only because I didn't know about the flex-forms that offer more customization than the hyperco.

As some of you know, I run the Flex-a-Form fiberglass leafs... mono-design, lightweight (approx 10 pounds each)... I discussed with Flex-a-Form my desires and intentions (SCCA autocrossing... national-level competition, class E/SP)... they wanted the 4-corner weights of the car particularly as I'd be driving/competing. From that figure, they recommended 225 pounds per inch, with a 5" in free arch (uncompressed)... settled at about 1-1/2" arch (compressed, but later settled flatter after a few months. Poly front/rear bushings. If I'd do it again, I would go slightly stiffer (~250 with a 4" arch, which would still settle close to flat after a while. The fiberglass leafs are supposed to give quicker response/reaction. I've been pleased... have run these on the car since mid-late 1980s.
Keep in mind, that I also run 1.24" diameter torsion bars (rated at 425 pounds per inch... after trying several smaller TBs), and I have adjustable Koni shocks, and the car's main intention is competition autocrossing (pylon and hi-speed tracks)... and its still comfortble on the highway cruising (avoiding streets with rough surfaces).
